I'm modeling a plate that will be bent 360° and seam welded. I can't seem to the bend to revolve without interference. Any thoughts?
I've been trying this. The Issue is the overlap even at the exacting length.
cut away the overlap and then show flat pattern???
Is this what you are after?
Happy to send the part if needed
Not with the lapping for weld. We're using a seam weld.
I was able to get rid of the error, but the overlap graphical display is still there.
FYI The second picture without the overlap is what it should look like prior to welding.
As you can see I can't figure out how to get rid of that silly overlap issue, although it shows the seam as It should... i'm actually shaking my head...
What kind of plate you're trying to make? Can you start with sheet metal and then add other features?
Just as you see above Deepak. I edited the original post to have a pretty picture for you.
Is your Material going in or out?
can you upload the file?
Material is being seam welded.
it appears that you need to have decent amount of flat left on the fixed face, or it fails???
Can you start with a bent plate and then flatten it to add cut feature?
I tried that, but SW asks for a fixed point or plane to create the flat plate??
that's where my method fell down.
Here is a example done in SW2017 (can do in lower version if needed)
Still showing a overlap, even with the length mathematically exactly as it should be.
Although I don't get a rebuild error anymore.
I suspect what you did is calculate your flat by doing some math. You knew what o.d. or i.d. you wanted and figured out what you thought the blank length should be (circumference). Then did a sketch bend. Whatever,,, your material is is going to stretch thus the overlap (depending on your k-factor).. I would suggest you do as Deepak suggests. Start with a cylinder of the correct size (leave a small gap in an arc of 359.9° or so then flatten it to get your flat pattern size. Use a k-factor of .5 or so should get you real close.
Here is the way that I do this part. I put in the arc and dimension the diameter and then use an equation with the circumference and subtract around 0.005" from this length. Seems like this works pretty well for us.
